摘要：

A joint transform correlation system was proposed for color image recognition. The system utilized three liquid crystal display (LCD) panels to display red green blue (RGB) components of a color image. The results showed that the correlation peaks of the three color components were spatially separated and located at different positions, when different focal lengths for Fourier lenses of the RGB images were chosen.
